CVE-2026-94134

The Apache Airflow SSH provider hook contains a vulnerability where it disables SSH host-key verification by default. Unless a host_key is configured or no_host_key_check is explicitly set to false, the hook accepts any server key. This affects both SSH and SFTP connections and allows an attacker...

CVE-2026-94134 Apache Airflow SSH provider, Apache Airflow SFTP provider: SSH hook disables host-key verification by default

The Apache Airflow SSH provider hook disables SSH host-key verification by default: unless hostkey is configured or nohostkeycheck is explicitly set to false, it accepts any server key. This affects SSH and SFTP connections that rely on the default. An attacker in a machine-in-the-middle position...
